Weight & Balance Calculator
Compute CG (center of gravity) from station weights — verify against forward/aft limits.
How to Use
- Add a row for each loading station (pilot, passengers, bags, fuel).
- Enter weight and arm.
- CG is computed as Σ(W·A) / Σ(W).

Summary
Formula
Moment
M = W × A (lb-in)
CG
CG = ΣM / ΣW
Within limits?
Forward ≤ CG ≤ aft AND total W ≤ max
Fuel weight
Avgas: 6.0 lb/gal · Jet-A: 6.7 lb/gal
